Abstract:
We use a compilation of redshifts of rich clusters by Andernach, Tago
and Stengler-Larrea (1996, in preparation) to determine superclusters
of rich clusters up to a redshift of z=0.12. Superclusters were
searched for with a clustering algorithm, using a neighbourhood radius
of 24h-1Mpc (h is the Hubble constant in units of 100km/s/Mpc).
The catalogue contains 220 superclusters of rich clusters, of which
90 superclusters have been determined for the first time. Table A2
gives the supercluster number, its multiplicity, centre coordinates, a
list of member clusters and identifications with the catalogue by
Einasto et al. (1994MNRAS.269..301E 1994MNRAS.269..301E).

--------------------------------------------------------------------------------
Note (1): c stands for supercluster candidate, i.e. a supercluster
in which less than two member clusters have a redshift measured
Note (2): the meaning of the flag is:
"e" indicates a cluster with estimated redshift
"-" indicates a cluster which would not be a supercluster
member if one had used only clusters with measured redshifts
in the search algorithm
